Specification forming part of Letters Patent No. 182,434, dated September 19, 1876; applicationled July 20, 1876.

.To all whom it may concern:

which rises and falls in unison with the iutermittent projection of the feed device above the table, so that the feed of the sole is effected by being raised from and carried forward over the table against a yielding knife-holder, which affords a cushioned resistance to relieve the jar of the intermittent action of the feed upon the sole. The presser-foot constantly rests upon the sole, whether the latter be raised from the table or restingA upon it, and when in this position it is released -from the feed 1and can be easily and quickly turned to Vfollow the curves of the sole. I thus combine with a feed device, which raises the sole to feed it over a fixed table, a channelknife, which is raised and lowered by the action of the feed device upon the sole, and thereby cutting a uniform depth of channel i in soles of different and varying thicknesses.

The knife is adjustable independently of the presser foot, to cut channels of different depths. The presser-foot is. carried by a stem in a socketedA head of the frame, and stands directly over the feed device, which consists of alternately-operating dogs, the seizingteeth of which operate with a four-motion feed through slots in the table, which serve to keep the teeth from being clogged with the fleshy part of the sole, the teeth for this purpose being arranged to operate in and out of separate slots and between bars, so as to clear -them of any adhering particles and insure their taking hold of the sole and feeding it along.

The edgerest for determining the line of the channel is combined with and carried by the presser-foot, and, like the channelknife, rises and falls -with said foot, so that the sole, while maintaining its contact with the presser-foot while being fed over the table by the upward pressure of the feed-dogs, also keeps its contact with the edge-rest, and thesole is fed against the' knife while it is held against the presser-foot and the edge rest, and free from pressure upon the table. The combination of the presser-foot, carrying both the channelknife and the edge-guide, with the fixed table, through slots in which the fourmotion dogfeed is arranged' for co-operation 'in making both the feed andthe channel when the sole :is raised fromthe table by the feed, constitutes the distinguishing matter of my invention, and enables me to cut a uniform depth of channel, with perfect facility for turning the sole without injury.

The `presser -foot and channelknife are raised by a lever and treadle connection to place the sole in position for operation. The four -motion feed f dogs may be operated in any suitable manner, so long as their feed functionv is in connection with a fixed slotted table and a presser-foot which carries the channel-knife above said table with a vertical movement, regulated and controlled by that of the lower feed device, through the intervention of the sole being channeled.

A projection on the under side of the presser-foot rests upon the table, and serves as a stop to limit the descent of the presser foot and channel-knife in relation to the surface of the table.

represents a partial sectional elevation of a sole-,channeling machine embracing my invention, the feed device being shown as projected above the table to raise the sole, and with it the channel-knife, in their proper relative and co-operative positions for both feeding and channeling; Fig. 2, a side view, the feed device being retracted beneath the table, and the sole resting thereon, free from the upward pressure of the feed. Figs. 3 and 4 are vertical sectional views taken at right; angles to Figs. 1 and 2, and in which the positions of the operating devices correspond thereto;

In the accompanying drawings, Figure 1l Figs. 5 and 6, enlarged detail views corresponding'tonigs. 3 and 4,; and Fig. 7, one of the-dog-carry-ing arms, showing-the manner of securing the dog-plate thereto.

A standard, A, rising from a bed-plate, A2, supports the several parts of the machine, and is suitably secured upon a bench. A head, B, from the standard supports and carries a ver- -tically-actingl presser-foot, G, to which the -presser-foot C and its channel-knife Dand the four-motion feed device is arranged a fixed slotted table, H, Fig. 8, over andupon which the sole is fed while being channeled, and with respect to which the channel-knife D is made to rise and fall by the direct action of the feed device upon the lower side-of the sole to feed the latter forward against the knife and maintain a uniform depth of channel in the sole while being so fed.

lThe table H is screwed to a projection from the standard, and has a series of parallel slots formed by bars t at right angles to the cutting-edge of the channel-knife, and into these slots the dog-teeth b are arranged to work -with what vis 'known as a four-motion feed upon the under side of the sole. These dog-teeth lare formed by slotted plates bolted to the upper ends of stout carrying-arms E E, arranged contiguous to each other upon eccentric bearings F F, the action of which, in connection with a fulcrum-bolt, J, intermediate with re-k spect to the dog-teeth andthe eccentrics, give the desired 'alternate feed to the dog-teeth b by reason of the opposite action of the eccenltries', and cause said teeth or dog-plates to rise and move forward in the table-slots and betweeuthe bars a, with their teeth describing the arc of a circle, and thus carry the sole with them against the channel-knife.V The dog-carrying arms E 'E have slots c, into which are fitted fulcrum-blocks d to render the action of the carrying-arms E steady and.

uniform. The fulcrum-boltJ serves to confine the fuicram-blocks and the carrying-dog arms in working-relation, lwhile their bearingeuds are extended' to form long boxes f, within which the -eccentrics F work, and, in connection with the fulcrum-blocks d, render the action of the slotted dog-plates b, with the slotted table, absolutely true, and without danger of injury t0 the dog-teeth. The eccentric shaft Gr carries a pinion, K, into which a large cranked gear, L, ,meshes at the back of the standard, while a balance-wheel, M, on the other end of the 'eccentric shaft, serves to render the motionv of the feed-dogs uniform.

The slotted'dog-plates b are secured in recesses in their carrying-arms E by clamp- '.plates g and screws h, which gives the advantage of removing and replacing the dog-plates whenever it may be necessary from any cause to do so. In doingthis it is only necessary to remove the fulcrum-bolt J, and turn do wnthe dog-carrying arms E from beneath the table.

The presser-foot G, in the example shown, consists A of an oblong carrier-block foi` the channel-knifel and the edge-rest. Its lower portion fi forms a comparatively narrowl pressing surface, which is in contact with the 'sole during the operation of channelin g, and against which it is pressed upward and fed by the dog-teeth; It has a vertical movement upon a stern, N, which rises into a socket, O, in the standard-head B-a side extension, B2, from which serves as a guide to keep the block in position for the proper action of the channelknife.

against the, side of the presser-foot by a clamp- The shank of this knife is confined plate, P, and screw j, so that its cutting-edge stands slanting to the table, and by which it can be adj usted to cut the channel the proper depth in soles `of different thicknesses;

A coil-spring, Q, is tted in the hollow standard-headB, so as to bear upon the stem N, and 'give the proper pressure upon the presser-foot. A stop, 7o, on its under side-in this instance formed by the shank of the edgerest--limits -the descent ofthe presser-foot,

and prevents the knife from striking the,

table.

The edge-rest R for the sole is adjustably secured to the under side of the presser-foot O, just back of the knife-shank, and rises and falls with the foot in an opening in the table. This construction gives the advantage of having the edge-rest move vertically with the sole as it is raised from the table against the pressure of the presser-foot, and fed in contact with it and the edge-rest by the four-motion feeddogs striking the under side of the sole and raising it from the ltable, lifting also the presser-foot with its channel-knife and edgerest nearly the same distance above the table as the projection of the feed-dogs, and cutting the channel in the sole, while the latter is pressed forward against the knife, and in which the presser-foot controls the depth :of the cut, and the edge-rest the line of the channel, which advantage is gained by the combination of the channel-knife with the presserfoot and the lifting-feed.

In placing the sole in position for work, the

presser-foot and its channel-knife are raised by means of a treadle-lever, S, pivoted to the standard, and extending beneath apin, l, projecting from the presser-foot stem N through an oblong opening, m, in the standard-head,

while its rear end is connected to the treadle descend below the surface of the table'l at a time, and thus give a free surface on which to turn the sole. This. is very important, not
